IPC: A01K31/00
Filed: 1916-05-12
Abstract: 102,326. Laye, H. R. de. May 12, 1916. Folding crates for poultry &c. comprise a bottom 1 having upstanding strips 2 on its side edges, to which are hinged side panels 3 formed with grooves 4 registering with grooves 5 in the strips. End panels 8, shown in the collapsed form of the crate in Fig. 5, are received in the grooves 4, 5 when the crate is set up, threaded studs 6 on the panels 3 are received in openings in a top panel 9, and nuts are screwed upon the studs.

Title: An improved machine for laying land drainage tiles
IPC: E02F5/14
Filed: 1954-03-09
Abstract: 786,737. Agricultural implements. COOPER, E. (Representative of COOPER T.). June 6, 1955 [March 9, 1954], No. 6839/54. Class 6(1). [Also in Group XXVIII] A machine for laying land drainage tiles T includes a share or coulter 1 with its leading edge set to cut through the earth vertically, a channel forming tool 2a carried by the lower end of the share or coulter, means in association with the latter for progressively pushing aside or expanding the earth at opposite sides of the vertical cut in such a way as to open up a temporary trench communicating with the drain channel moulded by the tool and down which trench tiles can be fed for laying and at opposite sides of the share or coulter, members 4 adapted to lift the earth at a location immediately above but behind the leading end of the tool. The lifting members function to deflect and lift the soil, this upwardly displaced soil in passing over the members at locations to the rear of the nose of the tool applying a downward thrust sufficient to force the working section of the machine into the ground and maintain it at the required depth. The rear end of the tool is held down. The working depth may be at least three feet six inches. As shown, the means for expanding the earth at opposite sides of the vertical cut consist of a pair of rearwardly divergent spreader plates 3 secured to the rear edge of the share or coulter. The tiles are fed by hand down an inclined slideway 12. The tool and the spreader plates may be welded to the share or coulter. The sides 7 at their rear ends are braced by a system of transverse ties. Holes 21 are provided for attachment of a beam 24. The rear end of the beam is supported by means of cables 34 which can be wound on drums 37 to lift the entire working section out of the ground. The drums are operated by handles 41. At its leading end the beam 24 is connected with means for controlling and varying its height above the ground. For this purpose apparatus of the character described in Specification 748,086 may be employed. The apparatus is in the form of a bridge 44, the lower ends of which are mounted on skids 45. The front end of the beam is suspended from the movable component of a hydraulic jack 46. The apparatus enables the top of a sighting rod 50 on the beam to be kept in line with the tops of two further sighting rods erected at remote and intermediate points. Hinged to the front of the beam is a draw attachment 52. A beam and carriage such as that described in Specification 748,086 can be used in conjunction with the above described tile layer. The tile layer would be suitable for laying tiles of various sizes. At its leading end, the beam may be provided with surface cutting knives (not shown). A pair of telescopic stay members 31 are disposed between the lower end of a bridge-like section 28 and a rectangular frame 29. Screw mechanisms are provided to vary the effective length of the stay members 31.

Title: Method of and apparatus for liquid transportation in continuous extraction apparatus
IPC: B01D11/04
Filed: 1961-02-24
Abstract: The apparatus of the parent Specification is modified by including in the connecting lines 12 an upwardly directed U-shaped conduit.  The transport of liquid during each pulse is such that a substantial part of the mixture in each U-conduit is transferred to an adjoining downwardly directed conduit.  Thus the volume of the pulse need only be larger than or the same magnitude as the volume of each downwardly directed conduit.  Specification 896,959 also is referred to.

Title: Improvements relating to the sintering of particulate materials in vertical shaft kilns
Inventor: GRIBBIN WALTER
IPC: F27B1/00
Filed: 1961-02-28
Abstract: A method of sintering particulate material such as fly ash or clay for cement comprises charging the material into a vertical shaft kiln of the type having a refractory body 12 penetrating into and through the firebed 4 which is formed at the upper level of material in the furnace (see Division F4). The refractory body 12 may serve for the supply of auxiliary combustion air or for the removal of exhaust gases and in addition creates a vertical tunnel or shaft 14 substantially free of material in the downwardly moving mass 3 of sintered material. This tunnel promotes even distribution of the combustion air to the firebed.  Sintered material is discharged at the base of the furnace. Two or more refractory bodies may be used creating a corresponding number of vertical tunnels for the upflow and distribution of combustion air. <PICT:0948804/C1/1>

In an anti-skid regulating device for the brake apparatus of hollow-axle rail vehicles, the device is fitted into the hollow axle and the parts supporting the device serve to drive same. In the embodiment illustrated, the regulating device comprises a cylindrical base 1 which is fitted into the bore 2 of an axle 3 and is secured thereto. Secured to the base 1 is a hollow regulator shaft 6 on which is rotatably mounted an inertia disc 7. A roller 10 is urged by spring 11 acting on control member 13, which is non-rotatable but axially movable on shaft 6, against a cam path 9 on inertia disc 7 such that rotation of control member 13 is transmitted positively to the inertia disc 7. Mounted in bearings 15 is a stationary hollow spindle 14 which extends through hollow regulator shaft 6 and which is secured to the bogey or vehicle chassis by tubular member 20 carrying electric leads 21. These leads are connected to spring contact arms 17. When the wheel is rotating normally, the spring-loaded roller 10 is situated in the lowest position of the cam path 9 of the inertia disc 7. However, when retardation reaches a predetermined value, the control member 13 is moved so far to the right, as a result of the roller 10 running up path 9, that the contact disc 18 is urged against the spring contact arms 17 such that brake release is effected via electric leads 21. A cylindrical protective cover 22 is secured to the base of the regulating device and packing 23 is arranged between the base 1 and spindle 14 to prevent entry of dirt.
